Kinematic Mount Resolution calculator

Angular tilt per rev/turn from screw pitch and lever arm.

Category: Optomechanics

Formula: Δθ = pitch / (arm) per full turn

Inputs

InputParameterUnitDefault
Threads per inchTPI100
Lever armarmmm25.4
Knob fractionfrac0.01

Result with the default inputs

  • Per full turn: 10 mrad
  • Per 0.01 turn: 100 µrad

Open it with your own values: put each input in the address as a parameter, for example /calculators/kinematic-mount-resolution?TPI=100. A unit other than the listed one goes in <parameter>_unit.
